On July 17, 2009, Mozilla posted mockup designs for the Windows version of Firefox 3.7. The first alpha of version 3.7 was released on February 10, 2010. Updates include use of Aero glass effects on Windows Vista and Windows 7. Mockups for Linux and Mac OS X have also been posted. Firefox 3.7 may be released in May-June 2010, and use the Gecko 1.9.3 engine. Mozilla has made unofficial "nightly builds" (the trunk builds referred to as Minefield) available for download on the Mozilla FTP Server.
On January 15, 2010 Mike Beltzner responded in a blog post to rumors that Mozilla planned "to drop Firefox 3.7 from its schedule", stating that "The rumours of Firefox 3.7’s demise have been greatly exaggerated."
